4. State and explain Gay Lussac's law of combinningvolumes. |
|
Answer» The law of combining volumes states that, when gases react together to form other gases, and when all volumes are measured at the same temperature and pressure The ratio between the volumes of the reactant gases and the gaseous products can be expressed in simplewhole numbers. For example, Gay-Lussac found that 2 volumes of hydrogen and 1 volume of oxygen would react to form 2 volumes of gaseous water. Based on Gay-Lussac's results,Amedeo Avogadrotheorized that, at the same temperature and pressure, equal volumes of gas contain equal numbers of molecules (Avogadro's law). This hypothesis meant that the previously stated result 2 volumes of hydrogen + 1 volume of oxygen = 2 volumes of gaseous water could also be expressed as 2 molecules of hydrogen + 1 molecule of oxygen = 2 molecules of water. how u find ans |
